Fixed dental prosthesis is a solution which offers high-quality dental replacement to the patient Apart from its durability, they create a comfortable and natural feel.
The main causes of tooth or dental crown loss are usually cavities and periodontitis. Decay destroys the hard tissues of the teeth (enamel and dentin), while periodontitis is an infection that damages the bone that supports the teeth, and if left untreated, it can lead to the loss of the whole tooth (both the root and the crown).
Dental crown and bridge procedures begin with the shaping of the tooth, then a dental impression will be taken and a dental laboratory will fabricate a replacement which will be cemented into place. Sometimes it will first be necessary to treat any decay on the teeth which the bridge will be attached to and possibly strengthen those teeth with restorations.
After shaping, the teeth are very sensitive, so a temporary crown or bridge will be put into place to cover the prepared tooth while the permanent crown or bridge is being made.
Ceramic crowns are fixed prosthetic devices that imitate the dental crown. We use them when the tooth is severely damaged, is missing a part or is esthetically unappealing, but the tooth root is still strong and healthy.
The affected tooth will first be shaped, then a dental impression will be made and a dental lab will fabricate a ceramic crown which will be similar in shape and color to the surrounding natural teeth.
Dental crown bases are available in a range of materials, from metal, zirconium to all-ceramic.
Ceramics in restorations are invaluable for use in the oral environment because ceramics is exceptionally strong and durable, it has a high resistance to temperature changes and corrosion, it is a weak electric conductor, and most importantly, it is biocompatible. It seldom causes allergic reactions, has an outstanding esthetic and is very natural-looking, which is why ceramics is an excellent choice of material for dental crowns and bridges.
Ceramic crowns can be divided into groups depending on the material used during fabrication:
- Metal-ceramic dental crowns – are known in prosthetic dentistry for their great strength and durability, pleasing esthetics and are a financially feasible solution to the patient. A disadvantage may be a visible dark grey line right at the crown’s edge due to the metal that lies underneath the crown’s surface, spoiling the crown’s appearance.
- Zirconium-ceramic dental crowns – are known for extraordinary strength and stability, excellent biocompatibility (do not cause allergies or reactions of surrounding tissue) and high esthetic appeal. The zirconium base underneath the ceramic crown is white and translucent, blending well with the tooth’s natural color.
- No-metal ceramic crowns – are a good choice for front teeth due to their highly esthetic features. They are very similar to a natural tooth and reflect light in the same way, allowing light to pass as a normal tooth would. The transparent color of no-metal ceramic crowns (Emax) ensure that they complement the rest of your natural teeth and is why they are the preferred crown among dentists.
A dental bridge is a fixed prosthetic device that is used to span any area of the mouth where one or more teeth are missing. A bridge is supported by natural teeth (compared to a bridge placed on dental implants) which are filed down and the bridge is cemented into place. This ensures the patient retains a natural feel in the mouth because the bridge is anchored to natural teeth which allow for normal functioning of the nerve and jawbone.
A dental bridge will help prevent the remaining teeth from shifting, it will restore your smile and help restore the ability to chew and speak naturally. The ceramic bridge base can be zirconium or metal.
Removable prosthetic devices
are used to replace all of the teeth in the patient’s mouth in the upper and lower jaw and lies directly on the gums. The dentures are made of acrylic (a kind of plastic) and are attached to the roof of the mouth by creating a suction seal.
Complete dentures are used when the patient is missing a full arch of teeth. The advantages of complete dentures are the affordable price and a short treatment time from start to finish. However, prolonged denture wearing can produce bone atrophy and can cause a decline in the fit of the dentures. These changes to the jawbone can prevent later implant-supported dentures.
are used when the patient is missing only some teeth. A partial denture can have clasps that connect it to the rest of the teeth. Hidden clasps can often be used instead of metal ones for esthetic reasons, as they are nearly invisible. Telescopic dentures can also be made, covering the remaining teeth inside the mouth.
